Skin specimens from 10 dolphins were studied with B-mode ultrasonography. The epidermal and hypodermal layers were defined, measured, and compared with measurements of actual tissue and with histologic measurements. Measurements of skin from six body zones of three live dolphins showed larger values but the same echogenic characteristics. B-mode measurements were found to be accurate and to provide visually acceptable information for use in evaluating the health status of these animals. The detection of a skin parasite by B-mode ultrasonography is also presented.
